Organic cadmium pigments are based on carbon chains and rings. While some contain inorganic elements as stabilizers, organic cadmium pigments are defined primarily by this factor. These strong carbon chains also make them highly stable.
Carbon-based cadmium pigments are derived from animals, vegetables or synthetic organic chemistry. While traditional cadmium pigments were typically created using flora and fauna, the majority of modern cadmium pigments are created through synthetic organic chemistry. Synthetic organic cadmium pigments are most commonly derived from aromatic hydrocarbons including coal tars and other petrochemicals.
Organic cadmium pigments are marked by the following qualities:
- Color quality: While most organic cadmium pigments are considered transparent, their tonality is
unparallelled. Organic cadmium pigments are characterized by bright, rich colors. They often
provide powerful tint strength despite their transparency.
- High prices: Organic cadmium pigments tend to be more expensive to produce, especially
synthetic organic cadmium pigments. Synthetic cadmium pigments require a great deal of chemical
processing to produce, increasing the cost by volume.
- Varying lightfastness: There are many different varieties of organic cadmium pigments, but most
of them tend to hold up poorly when exposed to light. While some can resist light and
heat exposure well, many will fade over time.
Organic cadmium pigments tend to be less popular in most industries compared to inorganic cadmium pigments, with
the exception of artists’ paints. However, organic cadmium pigments are frequently used on a lesser scale
in combination with inorganic cadmium pigments as this method improves the color quality of a product.
